TECHNICAL FIELD

Embodiments of the present disclosure relate to the field of displaytechnologies and, in particular, to a display panel and a displaydevice.

BACKGROUND

In recent years, with the development of display panels, it has becomemore common to integrate a touch function into a display panel. Thereare mainly two types for integrating a touch structure into the displaypanel: an on-cell type and an in-cell type.

A display panel integrated with the touch function may be an organiclight-emitting diode (OLED) display panel or a liquid crystal display(LCD) panel. For the organic light-emitting display panel, the in-celltype means that a touch structure is on one side of the encapsulationglass facing an array substrate. However, a touch drive chip thatprovides a touch signal to the display panel is generally disposed onone side of the array substrate. To transmit the touch signal to thetouch structure, conductive structures are generally disposed on thearray substrate and the encapsulation glass. A conductive structure onthe array substrate is electrically connected to a touch drive chipthrough a metal wire, and a conductive structure on the encapsulationglass is electrically connected to the touch structure. When the coverglass is disposed opposite to the array substrate, the conductivestructures on the array substrate and the encapsulation glass areelectrically connected in contact so that the touch drive chip iselectrically connected to the touch electrode.

However, in the related art, a conductive structure may be recessed dueto manufacturing process, thus being higher in the periphery and lowerin the middle of the glass. That is, the conductive structure has anon-planar conductive contact surface so that there is a small effectivecontact area between the conductive structure on the array substrate andthe conductive structure on the encapsulation glass, thereby affectingthe effective conduction between the conductive structure on the arraysubstrate and the conductive structure on the encapsulation glass.

DETAILED DESCRIPTION

Hereinafter the present disclosure will be further described in detailin conjunction with the drawings and embodiments. It is to be understoodthat the embodiments set forth herein are merely intended to illustrateand not to limit the present disclosure. Additionally, it is to be notedthat for ease of description, merely part, not all, of the structuresrelated to the present disclosure are illustrated in the drawings.

FIG. 1 is a structural diagram of a touch display panel according to therelated art. FIG. 2 is a sectional view taken along a section line A-A′of FIG. 1. Referring to FIGS. 1 and 2, a touch display panel includes adisplay area DA′, a non-display area NA′, and a first substrate 110′ anda second substrate 210′ disposed opposite to the first substrate 110′.In the display area DA′, multiple touch electrodes 230′ are configuredto be on one side of the second substrate 210′ facing to the firstsubstrate 110′. In the non-display area NA′, multiple first conductivestructures 120′, multiple metal wires 130′ and a touch drive chip 30′are configured to be on one side of the first substrate 110′ facing tothe second substrate 210′. The multiple first conductive structures 120′are connected to the touch drive chip 30′ through the multiple metalwires 130′. Each first conductive structure 120′ generally includes afirst transmit electrode 121′ and a first gasket structure 122′ that isconfigured to raise the first transmit electrode 121′. The one side ofthe second substrate 210′ facing to the first substrate 110′ is providedwith multiple second conductive structures 220′. The multiple secondconductive structures 220′ are electrically connected to the multipletouch electrodes 230′ via touch wires 240′. Each second conductivestructure 220′ includes a second transmit electrode 221′. Since thefirst gasket structure 122′ raises the first transmit electrode 121′,the first transmit electrode 121′ and the second transmit electrode 221′can be electrically connected in contact so that the multiple touchelectrodes 230′ are electrically connected to the touch drive chip 30′,and thereby, touch signals generated by the touch drive chip 30′ can betransmitted to the multiple touch electrodes 230′. However, theapplicant has found that the first gasket structure 122′ is generallyformed by multiple stacked inorganic layers, metal layers and organiclayers, and when the multiple inorganic layers have a greater thickness,the multiple inorganic layers are easily higher in the periphery andlower in the middle due to uneven stress so that the first transmitelectrode 121′ is easily recessed in the middle. That is, each firstconductive structure 120′ is in a recessed state. Thus, each firstconductive structure 120′ is in contact with a respective secondconductive structure 220′ only in the periphery, and thereby theeffective conduction is affected.

In view of these, the present disclosure provides a touch display panel.The touch display includes a display area, a non-display area, and afirst substrate and a second substrate disposed opposite each other.

In the non-display area, multiple first conductive structures andmultiple metal wires are configured on one side of the first substratefacing to the second substrate, and multiple second conductivestructures are configured on one side of the second substrate facing tothe first substrate. Each first conductive structure is electricallyconnected to a respective second conductive structure. In the displayarea, multiple pixel units are configured on the one side of the firstsubstrate facing to the second substrate, and touch electrodes areconfigured on the one side of the second substrate facing to the firstsubstrate. The multiple second conductive structures are electricallyconnected to the touch electrodes. The multiple metal wires areconfigured to transmit touch signals.

Each first conductive structure includes a first transmit electrode anda first gasket structure, the first gasket structure is disposed betweenthe first transmit electrode and the first substrate. The first transmitelectrode is electrically connected to a metal wire and the respectiveone second conductive structure. The first gasket structure includesmultiple first recessed portions. A first support portion is disposedbetween two adjacent first recessed portions.

The above is the core idea of the present disclosure, and technicalsolutions in the embodiments of the present disclosure will be describedclearly and completely in conjunction with drawings in the embodimentsof the present disclosure. On the basis of the embodiments of thepresent disclosure, all other embodiments obtained by those skilled inthe art without creative work are within the scope of the embodiments ofthe present disclosure.

FIG. 3 is a structural diagram of a touch display panel according to anembodiment of the present disclosure. FIG. 4 is a cross sectional viewtaken along a section line B-B′ of FIG. 3. Referring to FIGS. 3 and 4,the touch display panel includes a display area DA, a non-display areaNA, and a first substrate 110 and a second substrate 310 disposedopposite to the first substrate 110. In the non-display area NA,multiple first conductive structures 20 and multiple metal wires 50 areconfigured on one side of the first substrate 110 facing to the secondsubstrate 310, and multiple second conductive structures 40 areconfigured on one side of the second substrate 310 facing to the firstsubstrate 110. Each first conductive structure 20 is electricallyconnected to a respective second conductive structure 40. In the displayarea DA, multiple pixel units 120 are configured on the one side of thefirst substrate 110 facing to the second substrate 310, and touchelectrodes 320 are configured on the one side of the second substrate310 facing to the first substrate 110. The multiple second conductivestructures 40 are electrically connected to the touch electrodes 320.The multiple metal wires 50 are configured to transmit touch signals.Each first conductive structure 20 includes a first transmit electrode220 and a first gasket structure 210 that is disposed between the firsttransmit electrode 220 and the first substrate 110. The first transmitelectrode 220 is electrically connected to a metal wire 50 and therespective one second conductive structure 40. The first gasketstructure includes multiple first recessed portions AX1. A first supportportion ZC1 is disposed between two adjacent first recessed portionsAX1.

Specifically, the display area DA may include multiple scan lines andmultiple data lines. The multiple scan lines and the multiple data linesintersect to define multiple sub-pixel areas. Each sub-pixel area isprovided with a sub-pixel. Each pixel unit 120 is composed of at leastone sub-pixel. The multiple pixel units 120 are scanned line by line sothat data signals can be written line by line. Then the multiple pixelunits 120 are lightened line by line, and thereby a frame of picture isdisplayed.

Specifically, the display area DA may further include multiple touchelectrodes 320. The multiple touch electrodes 320 are configured todetect a touch position of a user. FIG. 3 just shows the example of adisplay device with self-capacitive touch electrodes 320, but is notintended to limit the display device of the present disclosure. In otherembodiments, each touch electrode 320 may be mutual-capacitive, which isnot limited here and may be configured by those skilled in the artaccording to practical situations. If each touch electrode 320 isself-capacitive, the operating process of each touch electrode 320 isdescribed as follows. Each touch electrode 320 corresponds to a certaincoordinate position and produces capacitance together with the ground.When a finger touches the touch panel device, the capacitance of thefinger is superimposed on a touch electrode 320 that the finger touches,thereby causing a variation in the ground capacitance of the touchelectrode 320 that the finger touches. Since the signal variation ofeach touch electrode 320 reflects the variation of the groundcapacitance of each touch electrode 320, a touch electrode 320 whosesignal has undergone a variation can be determined through the detectionof the signal variation of each touch electrode 320, and then the touchposition of the finger can be determined on the basis of coordinates ofthe touch electrode 320 whose signal has undergone a variation. If eachtouch electrode 320 is mutual-capacitive, the operating process of eachtouch electrode 320 is described as follows. The mutual-capacitive touchelectrode 320 includes a horizontal electrode array and a verticalelectrode array. Capacitance is produced at crossing positions of thetwo sets of electrodes. When the finger touches the touch display panel,the coupling between two electrodes near a touch point is affected sothat the capacitance between the two electrodes undergoes a variation.During the detection of the mutual capacitance, a stimulation signal issequentially sent to each horizontal electrode, and each verticalelectrode receives the signal, so that capacitance values ofintersection points of horizontal electrodes and vertical electrodes,that is, capacitance values in the two-dimensional plane of the wholetouch display panel, can be obtained. According to the two-dimensionalcapacitance variation data of the touch display panel, the coordinatesof each touch point can be calculated, and then the touch position ofthe finger is determined.

Specifically, the non-display area NA may be configured to set a fan-outwire, an electrostatically shielded circuit, a lighting test circuit, agate drive circuit, a touch drive chip and other electronic elementsknown to those skilled in the art, which is not limited in the presentapplication.

Specifically, the touch signal may include a detection signal and afeedback signal. The detection signal is provided to each touchelectrode 320 by the touch drive chip. The feedback signal that carriestouch information is fed back to the touch drive chip by each touchelectrode 320. Therefore, it is necessary to electrically connect eachtouch electrode 320 to the touch drive chip. In the present application,after each first conductive structure 20 and the respective one secondconductive structure 40 are electrically connected in contact, thedetection signal provided by the touch drive chip may be transmitted toeach touch electrode 320 via the metal wire 50, a first conductivestructure 20 and a second conductive structure 40 in sequence. Thefeedback signal fed back by each touch electrode 320 may be transmittedto the touch drive chip via the second conductive structure 40, thefirst conductive structure 20 and the metal wire 50 in sequence. Thereare various ways for electrically connecting the touch drive chip to themetal wire 50, which can be configured by those skilled according toactual situations and is not limited here. Exemplarily, as shown in FIG.3, the one side of the first substrate 110 facing to the secondsubstrate 310 is further provided with bonding gasket structures 60, andeach bonding gasket structure 60 is electrically connected to the metalwire 50. Each bonding gasket structure 60 may be configured to bond thetouch driver chip so that the touch driver chip can be electricallyconnected to the metal wire 50 through each bonding gasket structure 60.Alternatively, each bonding gasket structure 60 may be configured tobond a flexible printed circuit board on which the touch drive chip isdisposed so that the touch drive chip can be electrically connected tothe metal wire 50 through a wire on the flexible printed circuit boardand each bonding gasket structure 60.

Specifically, to form each pixel unit 120, multiple films are generallyformed on the first substrate 110 in the display area DA. Exemplarily,the first substrate 110 may be provided with an active layer, a gateinsulating layer, a gate layer, an interlayer dielectric layer, asource-drain electrode layer and other films known to those skilled inthe art. It is to be understood that in the display area DA, themultiple films for forming each pixel unit 120 have a certain height. Inorder that the first conductive structure 20 is higher than the multiplefilms in total in the display area DA, the first conductive structure 20includes a first gasket structure 210 that is configured to raise thefirst transmit electrode 220. The first gasket structure 210 may beformed by multiple stacked films, where part of the multiple films ismade of an organic material. Since the organic material has a largerfluidity and a lower hardness, if the organic film in the first gasketstructure 210 has a greater height and a larger area, uneven stress iscommon during the film formation process, thereby causing a recess inthe middle, and finally the first transmit electrode 220 is recessed inthe middle, as shown in FIG. 2.

It is to be understood that in the present application, the multiplefirst recessed portions AX1 are formed on the first gasket structure 210so that the first support portion ZC1 can be formed between adjacentfirst recessed portions AX1. Although recessed in the middle, each firstsupport portion ZC1 is flat in the periphery, and thereby first supportportions ZC1 have a flat surface large enough in total. Therefore, thefirst transmit electrode 220 on the first gasket structure 210 has alarger flat surface, and there is a greater effective contact areabetween the first transmit electrode 220 and the second conductivestructure 40 when the first transmit electrode 220 is in contact withthe second conductive structure 40. Such configuration can reduce thecontact resistance between the first transmit electrode 220 and thesecond conductive structure 40, and improve the transmit rate of thefirst conductive structure 20 and the second conductive structure 40 forthe touch signal.

In the touch display panel provided by this embodiment of the presentdisclosure, the multiple first recessed portions AX1 are disposed on thefirst gasket structure 210 of the first conductive structure 20 so thatthe first support portion ZC1 is formed between the adjacent two firstrecessed portions AX1. Although recessed in the middle, each firstsupport portion ZC1 is flat in the periphery, and thereby first supportportions ZC1 have a flat surface large enough in total. Compared to therelated art, such configuration can improve the situation that the firsttransmit electrode 220 on the first gasket structure 210 is recessed inthe middle and enlarge the flat surface of the first transmit electrode220, thereby increasing the effective contact area between the firsttransmit electrode 220 and the second conductive structure 40, reducingthe contact resistance between the first transmit electrode 220 and thesecond conductive structure 40, and improving the transmit rate of thefirst conductive structure 20 and the second conductive structure 40 forthe touch signal.

FIG. 5 is another cross sectional view taken along a section line B-B′of FIG. 3. Referring to FIG. 5, optionally, each second conductivestructure 40 includes a second transmit electrode 420 and a secondgasket structure 410 that is disposed between the second transmitelectrode 420 and the second substrate 310. The second transmitelectrode 420 is electrically connected to the touch electrode 320 andthe first transmit electrode 220. The second gasket structure 410includes multiple second recessed portions AX2. A second support portionAC2 is disposed between adjacent second recessed portions AX2.

Specifically, in the display area DA, the multiple touch electrodes 320and a film for protecting each touch electrode 320 may be formed on thesecond substrate 310. In order that the first conductive structure 40 ishigher than stacked films in total in the display area DA, the secondconductive structure 40 includes the second gasket structure 410 that isconfigured to raise the second transmit electrode 420. The second gasketstructure 410 may be formed by multiple stacked films, where the secondgasket structure 410 may include or not include an organic film.

It is to be understood that if the second gasket structure 410 includesthe organic film, the second gasket structure 410 also is recessed inthe middle, and this is similar to the multiple first recessed portionsAX1 on the first gasket structure 210. In the present application, themultiple second recessed portions AX2 are formed on the second gasketstructure 210 so that the second support portion ZC2 is formed betweenthe adjacent second recessed portions AX2. In this way, second supportportions ZC2 can have a flat surface large enough in total so that thesecond transmit electrode 420 on the second gasket structure 410 has alarger flat surface, and there is a greater effective contact areabetween the first transmit electrode 200 and the second transmitelectrode 420 when the first transmit electrode 200 is disposed contactwith the second transmit electrode 420. Accordingly, such configurationfurther reduces the contact resistance between the first transmitelectrode 220 and the second transmit electrode 420 and improves thetransmit rate of the first conductive structure 20 and the secondconductive structure 40 for the touch signal.

It is to be noted that the number of first support portions ZC1, thenumber of first recessed portions AX1, and orthographic projection areasof the first support portions ZC1 and the multiple first recess AX1 ontothe first substrate may be configured by those skilled in the artaccording to practical situations, which is not limited in the presentapplication. Similarly, the number of second support portions ZC2, thenumber of second recessed portions AX2, and orthographic projectionareas of the second support portions ZC2 and the multiple secondrecessed portions AX2 onto the first substrate may be configured bythose skilled in the art according to practical situations.

On the basis of the preceding technical solution, specifically, when thefirst substrate 110 is disposed opposite to the second substrate 310 sothat each first conductive structure 20 and the respective secondconductive structure 40 are electrically connected in contact, theorthographic projection of the first support portion ZC1 onto the firstsubstrate 110 may be at least partially overlapped with the orthographicprojection of the second support portion ZC2 onto the first substrate110, or may be not overlapped with the orthographic projection of thesecond support portion ZC2 onto the first substrate 110 at all. Eachcase will be separately described below.

Firstly, optionally, the orthographic projection of the first supportportion ZC1 onto the first substrate 110 is at least partiallyoverlapped with the orthographic projection of the second supportportion ZC2 onto the first substrate 110. In this way, the part of thefirst transmit electrode 220 on the first support portion ZC1 and thepart of the second transmit electrode 420 on the second support portionZC2 can be electrically connected in contact.

FIG. 6 is a structural diagram of orthographic projections of firstsupport portions onto a first substrate 110 according to an embodimentof the present disclosure. FIG. 7 is a structural diagram oforthographic projections of first support portions onto a firstsubstrate 110 according to an embodiment of the present disclosure. FIG.8 is a position relationship diagram of orthographic projections offirst support portions and second support portions onto a firstsubstrate 110 according to an embodiment of the present disclosure.Referring to FIGS. 6 to 8, optionally, the orthographic projection ZC1′of the first support portion ZC1 onto the first substrate 110 iscompletely overlapped with the orthographic projection ZC2′ of thesecond support portion ZC2 onto the first substrate 110. Through suchconfiguration, the part of the first transmit electrode 220 on eachfirst support portion ZC1 and the second transmit electrode 420 have theopportunity to be electrically connected in contact, and this helpsincrease the effective contact area between the first transmit electrode220 and the second transmit electrode 420. Additionally, during themanufacturing process of the first support portion ZC1 and the secondsupport portion ZC2, it is feasible to use the same mask plate, therebysaving the number of mask plates for the manufacturing process of thetouch display panel and reducing manufacturing costs.

FIG. 9 is another position relationship diagram of orthographicprojections of first support portions ZC1 and second support portionsZC2 onto a first substrate 110 according to an embodiment of the presentdisclosure. Referring to FIG. 9, optionally, the first support portionsZC1 are not connected to each other, the second support portions ZC2 arenot connected to each other, each first support portion ZC1 correspondsto a respective second support portion ZC2, and the orthographicprojection ZC1′ of the first support portion ZC1 onto the firstsubstrate 110 is partially overlapped with the orthographic projectionZC2′ of the second support portion ZC2 onto the first substrate 110.Such configuration helps those skilled in the art flexibly configure thefirst support portion ZC1 and the second support portion ZC2 accordingto practical situations.

FIG. 10 is another position relationship diagram of orthographicprojections of first support portions ZC1 and second support portionsZC2 onto a first substrate 110 according to an embodiment of the presentdisclosure. referring to FIGS. 9 and 10, optionally, the orthographicprojection ZC1′ of the first support portion ZC1 onto the firstsubstrate 110 is within the orthographic projection ZC2′ of the secondsupport portion ZC2 onto the first substrate 110. Alternatively, theorthographic projection ZC2′ of the second support portion ZC2 onto thefirst substrate 110 is within the orthographic projection ZC1′ of thefirst support portion ZC1 onto the first substrate 110.

It is to be noted that the description that the orthographic projectionZC1′ of the first support portion ZC1 onto the first substrate 110 iswithin the orthographic projection ZC2′ of the second support portionZC2 onto the first substrate 110 here refers to the relationship betweenthe orthographic projection of the first support portion ZC1 and theorthographic projection of the second support portion ZC2 onto the firstsubstrate 110 when the first support portion ZC1 is aligned with thesecond support portion ZC2 without deviation according to thetheoretical design. This is similar to the description that theorthographic projection ZC2′ of the second support portion ZC2 onto thefirst substrate 110 is within the orthographic projection ZC1′ of thefirst support portion ZC1 onto the first substrate 110, which is notrepeated here.

It is to be understood that after each film on the first substrate 110and the second substrate 310 is separately manufactured, during theprocess of disposing the first substrate 110 and the second substrate310 opposite to each other in combination to form a touch display panel,the first substrate 110 may be misaligned with and the second substrate310. When the first substrate 110 is misaligned with the secondsubstrate 310, each first conductive structure 20 is misaligned with therespective second conductive structure 40, and thereby, the alignmentarea between the first support portion ZC1 and the second supportportion ZC2 may be reduced. In theory, the orthographic projection ZC1‘of the first support portion ZC1 onto the first substrate 110 is withinthe orthographic projection ZC2’ of the second support portion ZC2 ontothe first substrate 110 to reduce the probability that a part of thefirst support portion ZC1 is aligned with a second recess AX2 when thefirst substrate 110 is misaligned with the second substrate 310. Inother words, such configuration can improve the probability that thepractical aligned area between the first support portion ZC1 and thesecond support portion ZC2 is equal to the theoretical aligned area.This can increase the probability that the part of the first transmitelectrode 220 on each first support portion ZC1 is disposed contact withthe second transmit electrode 420, and ensure an effective contact arealarge enough between the first transmit electrode 220 and the secondtransmit electrode 420. Similarly, the same effect can be achieved ifthe orthographic projection ZC2′ of the second support portion ZC2 ontothe first substrate 110 is configured within the orthographic projectionZC1′ of the first support portion ZC1 onto the first substrate 110,which is not repeated here.

FIG. 11 is another position relationship diagram of orthographicprojections of first support portions and second support portions onto afirst substrate according to an embodiment of the present disclosure.Referring to FIGS. 9 and 11, optionally, the orthographic projectionZC1′ of a center point of the first support portion ZC1 onto the firstsubstrate 110 is coincident with the orthographic projection ZC2′ of acenter point of the second support portion ZC2 onto the first substrate110.

It is to be noted that the description that the orthographic projectionZC1′ of the center point of the first support portion ZC1 onto the firstsubstrate 110 is coincident with the orthographic projection ZC2′ of thecenter point of the second support portion ZC2 onto the first substrate110 here refers to the relationship between the orthographic projectionof the first support portion ZC1 and the orthographic projection of thesecond support portion ZC2 onto the first substrate 110 when the firstsupport portion ZC1 is aligned with the second support portion ZC2without deviation according to the theoretical design.

Such configuration can reduce the risk that the part of the firstsupport portion ZC1 is aligned with the second recess portions AX2 whenthe first substrate 110 is misaligned with the second substrate 310,thereby improving the probability that the practical aligned areabetween the first support portion ZC1 and the second support portion ZC2is equal to the theoretical aligned area, and ensuring an effectivecontact area large enough between the first transmit electrode 220 andthe second transmit electrode 420.

Next, optionally, the orthographic projection of the first supportportion ZC1 onto the first substrate 110 is at least partiallyoverlapped with the orthographic projection of the second recessedportion AX2 onto the first substrate 110. That is, the orthographicprojection of the first support portion ZC1 onto the first substrate 110is not overlapped with the orthographic projection of the second supportportion ZC2 onto the first substrate 110 at all. In this way, when thefirst support portion ZC1 is higher than the second support portion ZC2,the part of the first transmit electrode 220 on the first supportportion ZC1 and the part of the second transmit electrode on the secondrecessed portion AX2 may be electrically connected in contact; and whenthe first support portion ZC1 is lower than the second support portionZC2, the part of the first transmit electrode 220 on a first recess AX1and the part of the second transmit electrode on the second supportportion ZC2 may be electrically connected in contact.

FIG. 12 is another cross sectional view taken along a section line B-B′of FIG. 3. Referring to FIG. 12, optionally, the orthographic projectionof the first support portion ZC1 onto the first substrate 110 is atleast partially overlapped with the orthographic projection of thesecond recessed portion AX2 onto the first substrate 110. Through suchconfiguration, those skilled in the art can flexibly configure the firstsupport portion ZC1 and the second recessed portion AX2 according topractical situations. Additionally, when the first substrate 110 ismisaligned with the second substrate 310 (where the alignment deviationis within the allowable range), the fitting between each firstconductive structure 20 and the respective one second conductivestructure 40 is not affected.

FIG. 13 is another cross sectional view taken along a section line B-B′of FIG. 3. Referring to FIG. 13, optionally, the orthographic projectionof the first support portion ZC1 onto the first substrate 110 iscompletely overlapped with the orthographic projection of the secondrecessed portion AX2 onto the first substrate 110. Through suchconfiguration, the part of the first transmit electrode 220 on thesidewall of the first support portion ZC1 and the part of the secondtransmit electrode 420 on the sidewall of the second recessed portionAX2 can be electrically connected in contact, and this helps increasethe effective contact area between the first transmit electrode 220 andthe second transmit electrode 420.

FIG. 14 is a cross sectional view taken along a section line B-B′ ofFIG. 3. Referring to FIG. 14, optionally, the first support portion ZC1has the same height as the second support portion ZC2 along thethickness direction of the display panel.
